BreatheDot: A Portable Meditation Aid via HackaDay

This is a small battery-powered meditation aid that is powered off a CR2032 battery. It uses an ATTiny85 and a single blue LED. By matching your breathing with the LED, you should feel the effects after 3 to 5 minutes.

The benefit of having a piece of hardware is that you can use it quickly and you don't have to strain your eyes looking at a screen.

It uses the box-breathing method used in yoga and the Navy Seals. Hopefully this project can help in promoting better health and well being.
